Plant I.d.

Asked August 30, 2018, 7:16 PM EDT

I was wondering if you could help me identify this plant? I saw it growing along side a stream just north of the Pennsylvania line. It was everywhere all along the stream banks. Thanks

This is called Japanese knotweed (Reynoutria japonica).
Unfortunately, it is a non-native invasive plant that is very difficult to control. Here is additional information about it as well as management options.
